Definitions

  • the present invention relates to locking devices, and can be used in particular for constricting devices for body parts, such as a vein constrictor.
  • a locking device such as for example a constricting device for body parts, which eliminates the disadvantages of the prior art.
  • a locking device comprising a band provided with a locking element on its one end; a housing; a rocker turnably movable relative to said housing and having an edge which in a closed position of the device applies pressure to the band and stops the band from movement, said locking element provided on said end of the band being engageable with said housing; first means for turning said rocker and releasing the pressure on the band so that the band is released and can be moved but said locking element can not disengage from said housing; and second separate means which, upon release of the pressure on the band and application of an action to said second unit by a user, release said locking element from said housing in a next step so as to disengage said element from said housing and to open the locking device.
  • the functions of releasing a tension of the band is separated from the function of opening of the arresting closure.
  • the device is designed so that first a key is pressed to release tension of the band, but the closure can not be open. Only thereafter by pushing of buttons provided in the device, the closure can be open.
  • the device is designed so that there are two independent steps in the operation of the device after its use. Upon pressing of the key the cap with the band can not “jump” as before, since the device is still not completely open. Only thereafter, when the buttons are pressed by the user, the cap attached to the end of the band is released and can be withdrawn from the housing without any unexpected movements of the parts of the device.
  • FIG. 1 is a side view of a locking device in accordance with the present invention
  • FIG. 2 is a plan view of the inventive locking device in accordance with the present invention.
  • FIG. 3 is a view schematically showing a position of the inventive locking device in which a band is clamped by a rocker of the inventive locking device;
  • FIG. 4 is a view showing the inventive locking device in which a pressure of the band is released, but a cap attached to one end of the band still can not be disengaged from a housing of the device;
  • FIG. 5 is a view showing the inventive locking device in a position in which, after releasing the tension of the band, the cap on one end of the band is disengaged from the housing;
  • FIG. 6 is a plan view and a side view of the inventive locking device in which a tongue of the cap moves toward a closed position, and hooks of the tongue are still not engaged behind arresting cams of two sliders connected to side buttons;
  • FIG. 7 is a plan view and a side view of the inventive locking device in a position in which the hooks of the tongue engage behind the arresting cams of the sliders, where there is no tension caused by a band;
  • FIG. 8 is a view showing the inventive locking device in a position which substantially corresponds to the position shown in FIG. 7 , but in which the band is under tension;
  • FIG. 9 is a plan view and a side view of the inventive locking device in a position in which the buttons are pushed toward one another to completely release a connection of the cap with the band from the housing.
  • a locking device in accordance with the present invention for example for constricting body parts, has a housing which is identified as a whole with reference numeral 1 .
  • a rocker 2 is mounted on the housing 1 pivotally around an axis formed for example by a pin 3 which extend through side walls of the housing 1 and the rocker 2 in assembled condition.
  • the locking device further has a band which is identified with reference numeral 4 and extends through a slot formed between the housing 1 and the rocker 2 .
  • the band 4 has one end 5 which a user can grasp so as to move the band 4 along the slot 2 to reduce a loop 6 formed by the band around a body part to be constricted.
  • An opposite end 7 of the band 4 is attached to a cap 8 provided with a tongue 9 which is engageable with and disengageable from the housing 1 .
  • Reference numeral 10 identifies a right edge of the rocker 2 .
  • a key 11 is provided on the rocker for pressing by a user and performing a first step of opening of the locking device as will be explained later on.
  • Two buttons 12 are further provided to be pressed by a user, to perform a second step for opening of the locking device as will be explained herein below.
  • Reference numeral 21 identifies a component which is associated with the rocker 2 and has a wedge-shaped portion associated with a wedge-shaped opening 22 in the housing 1 .
  • Two sliders 23 and 24 are further provided. They are movable relative to one another in a transverse direction and have hooks.
  • the slider 24 has a pin 25 while the slider 23 has an associated recess 26 .
  • a user introduces for example his arm into the loop 6 formed by the band 4 and pulls the band by its end 5 to the right in the drawing so as to reduce the loop 6 and to tighten it on the arm.
  • the rocker 2 turns around the axis of the pin 3 and its right edge 10 applies a pressure to the band 4 and clamps it in the position in which the loop 6 restricts the arm of the user, as shown in FIG. 3 .
  • the user presses the buttons 12 toward one another ( FIG. 2 ), and as a result the tongue 9 of the cap 8 is disengaged from the housing 1 , so that the locking device is opened and can be removed from the arm of a user.
  • the release of tension of the band 4 is performed in the first step shown in FIG. 4
  • the disengagement of the tongue 9 of the cap 8 from the housing 1 with opening of the device is performed in the second step shown in FIG. 5 .
  • the second step is separate and independent from the previous first step and can be performed only after the first step has been completed.
  • the wedge-shaped of the component 21 associated with the rocker 2 is offset relative to the wedge-shaped opening 22 in the housing 1 , while in the position shown in FIGS. 4 and 5 the wedge-shaped portion of the component 21 is completely engaged into the wedge-shaped opening 22 of the housing 1 .
  • the two sliders 23 and 24 of the locking device are movable relative to one another in a transverse direction in FIGS. 6-9 and are provided with the hooks.
  • FIG. 6 shows a position in which the tongue 9 is moved into the housing to close the device.
  • the tongue 9 engages with its hooks the hooks of the sliders 23 and 24 and therefore the loop 6 of the band is closed on the arm of the user and the device is in the closed condition.
  • the pin 25 of the slider 24 is disengaged from the recess 26 of the slider 23 .
  • the band 4 is not under tension yet. When thereafter a tension is provided in the band 4 by turning of the rocker, the pin 25 is displaced longitudinally relative to the recess 26 so that it can not engage in the recess anymore.
  • the buttons 12 can not be pressed toward one another in this position.
